Given the shattered.io demonstration of SHA-1 collision-creation, one of
my colleagues at work (where we use the github repo) asked if I might try
comparing a pristine svn head working copy against a (purportedly)
corresponding git repo.
For my first try, I created a shiny new local clone of the repo we
actually use internally, checked the latest entry (from "git log") that
showed a "Notes" field:
...
Notes:
svn path=/head/; revision=313813
and accordingly used "svn up -r 313813" to update the svn working copy
to (what shohld be) the same point.
I then issued:
diff -ru -I '\$FreeBSD.*\$' ../svn/src FreeBSD >/tmp/svn_git at 313813_diff.txt
While I rather expected the first "difference" identified:
Only in ../svn/src: .svn
I was quote surprised to find 64 more "Only in ../svn/src/...." lines.
(I have attached a copy of the file.)
Is this expected?
Then, after some discussion with my colleague, I directed a Web browser
to <https://github.com/freebsd/freebsd>, selected "Clone or download";
saw that "Download ZIP" was an option, and then -- on the command line
-- ran:
fetch https://github.com/freebsd/freebsd/archive/master.zip
which ran uneventfully.
A subsequent:
unzip master.zip
nattered on at some length about inflating, creating, extracting various
file system-resident objects rather uneventfully... until the end, which
looked like this:
...
inflating: freebsd-master/usr.sbin/zzz/zzz.8
inflating: freebsd-master/usr.sbin/zzz/zzz.sh
finishing deferred symbolic links:

Note that while Apple authorized^J# the Inuktitut localization mentioned above, it was not shipped with^J# Apple hardware, and was not otherwise supported by Apple. Fonts^J# conforming to the Mac OS Inuit character set are available from^J# Everson Typography (http://www.evertype.com/software/apple/).^J# Information about the use of this character set is available at ^J# http://www.evertype.com/standards/iu/.^J#^J# The Mac OS Inuit character set shares the script code smEthiopic^J# (28) with the Ethiopic encoding. To determine if the Inuktitut^J# encoding is being used, you must also check if the system region^J# code is 78, verNunavut.^J#^J# The Mac OS Inuit character set includes the full syllabic letter^J# repertoire required for Inuktitut; it is a subset of the Unified^J# Canadian Aboriginal Syllabics set encoded in Unicode. The encoding^J# is InuitSCII, designed by Doug Hitch for the Government of the ^J# Northwest Territories.^J#^J# The Mac OS Inuit character set also includes a number of characters^J# that were needed for the classic Mac OS user interface and^J# localization (e.g. ellipsis, bullet, copyright sign). All of the^J# characters in Mac OS Inuit that are also in the Mac OS Roman^J# encoding are at the same code point in both; this improves^J# application compatibility.^J#^J# Unicode mapping issues and notes:^J# ---------------------------------^J#^J# Details of mapping changes in each version:^J# -------------------------------------------^J#^J##################^J0x00 - 0x7E = 0x0000 -^J0x80 = 0x1403^J0x81 = 0x1404^J0x82 = 0x1405^J0x83 = 0x1406^J0x84 = 0x140A^J0x85 = 0x140B^J0x86 = 0x1431^J0x87 = 0x1432^J0x88 = 0x1433^J0x89 = 0x1434^J0x8A = 0x1438^J0x8B = 0x1439^J0x8C = 0x1449^J0x8D = 0x144E^J0x8E = 0x144F^J0x8F = 0x1450^J0x90 = 0x1451^J0x91 = 0x1455^J0x92 = 0x1456^J0x93 = 0x1466^J0x94 = 0x146D^J0x95 = 0x146E^J0x96 = 0x146F^J0x97 = 0x1470^J0x98 = 0x1472^J0x99 = 0x1473^J0x9A = 0x1483^J0x9B = 0x148B^J0x9C = 0x148C^J0x9D = 0x148D^J0x9E = 0x148E^J0x9F = 0x1490^J0xA0 = 0x1491^J0xA1 = 0x00B0^J0xA2 = 0x14A1^J0xA3 = 0x14A5^J0xA4 = 0x14A6^J0xA5 = 0x2022^J0xA6 = 0x00B6^J0xA7 = 0x14A7^J0xA8 = 0x00AE^J0xA9 = 0x00A9^J0xAA = 0x2122^J0xAB = 0x14A8^J0xAC = 0x14AA^J0xAD = 0x14AB^J0xAE = 0x14BB^J0xAF = 0x14C2^J0xB0 = 0x14C3^J0xB1 = 0x14C4^J0xB2 = 0x14C5^J0xB3 = 0x14C7^J0xB4 = 0x14C8^J0xB5 = 0x14D0^J0xB6 = 0x14EF^J0xB7 = 0x14F0^J0xB8 = 0x14F1^J0xB9 = 0x14F2^J0xBA = 0x14F4^J0xBB = 0x14F5^J0xBC = 0x1505^J0xBD = 0x14D5^J0xBE = 0x14D6^J0xBF = 0x14D7^J0xC0 = 0x14D8^J0xC1 = 0x14DA^J0xC2 = 0x14DB^J0xC3 = 0x14EA^J0xC4 = 0x1528^J0xC5 = 0x1529^J0xC6 = 0x152A^J0xC7 = 0x152B^J0xC8 = 0x152D^J0xC9 = 0x2026^J0xCA = 0x00A0^J0xCB = 0x152E^J0xCC = 0x153E^J0xCD = 0x1555^J0xCE = 0x1556^J0xCF = 0x1557^J0xD0 = 0x2013^J0xD1 = 0x2014^J0xD2 = 0x201C^J0xD3 = 0x201D^J0xD4 = 0x2018^J0xD5 = 0x2019^J0xD6 = 0x1558^J0xD7 = 0x1559^J0xD8 = 0x155A^J0xD9 = 0x155D^J0xDA = 0x1546^J0xDB = 0x1547^J0xDC = 0x1548^J0xDD = 0x1549^J0xDE = 0x154B^J0xDF = 0x154C^J0xE0 = 0x1550^J0xE1 = 0x157F^J0xE2 = 0x1580^J0xE3 = 0x1581^J0xE4 = 0x1582^J0xE5 = 0x1583^J0xE6 = 0x1584^J0xE7 = 0x1585^J0xE8 = 0x158F^J0xE9 = 0x1590^J0xEA = 0x1591^J0xEB = 0x1592^J0xEC = 0x1593^J0xED = 0x1594^J0xEE = 0x1595^J0xEF = 0x1671^J0xF0 = 0x1672^J0xF1 = 0x1673^J0xF2 = 0x1674^J0xF3 = 0x1675^J0xF4 = 0x1676^J0xF5 = 0x1596^J0xF6 = 0x15A0^J0xF7 = 0x15A1^J0xF8 = 0x15A2^J0xF9 = 0x15A3^J0xFA = 0x15A4^J0xFB = 0x15A5^J0xFC = 0x15A6^J0xFD = 0x157C^J0xFE = 0x0141^J0xFF = 0x0142^JEND_MAP^J

Are the whines expected? Is it also expected that the exit status
will be 0 when whines are issued?
Thanks!

How could one possibly "respect" a misogynist, racist, bullying con-man??!?
